'Page Cannot be Found" in OWA only for certain user

[mdcr]

We have Exchange 2003 Enterprise Ed on a 2003 server (not a DC) where almost everyone can access OWA from the internet. One particular user gets a double-paned window with both panes saying "The page cannot be found" when she tries to login to OWA. SO it looks like OWA is beginning to load the page, but before either of the panes can be populated with data, the error occurs. We're going to check the 404 error that the page references, but the fact that everyone else can connect tells me it might be that particular account. This is not the oldest nor newest user account, the format is the exact same as everyone else, and the email addresses for this account are the same too. Any ideas? Thanks!

Check her group memberships to someone else.
Check this happens on another computer outside the company in case it is the computer itself.
Check event log for any errors generated on the Exchange server.
Check ADUC for differences between her account and others.

the user has the OWA service/protocol enabled on her account? was it only over the internet or internally and externally?

good luck

Her group memberships are the same as multiple users, it has happened on multiple computers, both inside and outside the network. There are no errors on Exchange, but we are noticing a lot of 538 and 540 (logon and logoff) entries in the event viewer/security log for her account as opposed to any other accounts, like over 30 entries in less than a minute. As for OWA service enabled, she was able to log into OWA when we had 5.5, but now that we're on 2K3, she cannot...
